Math Kit

Multisensory tactile math for blind and low-vision children.

What the Math Kit is

  • Live at DJN · 150 students

The Math Kit is a multisensory tactile system for blind and low-vision children — numeracy, counting, measurement and place value through touch, Braille and spatial interaction.

Developed by Avishi Gupta and iteratively refined based on feedback from students and educators at partner institutions. Uses textured, child-safe materials.

Available at Divya Jyoti Niwas — a residential school for the blind, 150 students across two centres.
